SHEETREKLIGNING ATTAJCHMENTFOR it TYPEWRITERS Gaylord If Pierce, San Diego, Calif. Application January :30, lesiilseriainb. 141,304?- 3 Claims.

This invention relates to an attachment for typewriters.

An object of this invention is to provide an attachment for typewriters which will assist in accurately replacing or adjusting a sheet on the platen so that corrections or additions may be accurately made.

Another object of this invention is to provide an attachment of this kind which can be readily mounted on the type bar cover, either inside or outside of the cover.

A further object of this invention is to provide a re-location attachment which includes a retractible ind cator which is manually moved to an operative or inoperative position.

A further object of this invention is to provide a re-locating attachment of this kind which can be readily adjusted for mounting on various makes of typewriters.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a longitudinal section taken on the line |-l of Figure 3 through a paper locating device constructed according to an embodiment of this invention.

Figure 2 is a sectional view taken on the line 2--2 of Figure 1;

Figure 3 is a sectional view taken on the line 83 of Figure 1; v

Figure 4 is a fragmentary perspective view partly in section showing the manner in which the device operates to relocate paper on the typewriter platen.

Referring to the drawing, the numeral l designates generally a conventional typewriter which is fragmentarily shown and is formed with a cover ll normally disposed over the type bars. A platen I2 is positioned rearwardly of the cover In order to provide a means whereby a paper sheet l3 may be relocated on the platen l2 in a correct position for either making corrections or for additional typing on the sheet, I have provided a pointer l4 which is disposed in confronting position to the paper l3 and is disposed in a horizontal plane coplanar with the writingline and preferably is disposed in a position for confronting a period or comma l5 or the bottom center of another character which may be typed on the paper sheet l3. The pointer I4 is secured to an upwardly projecting link I 6 by fastening means 2 I1, and the link I6 is secured to an upwardly projecting ear I 8 by fastening means IS.

The ear l8 extends upwardly from a base 20 which is secured by fastening means 2| to an upwardly projecting lug 22 carried by an elongated slide bar 23. The slide bar 23 is slidable in a pair of guide bars 24 carried by the side walls 25 of a housing 26. The housing 26 has an elongated slot 21 in the top wall 28 thereof through which the lug 22 slidably engages.

The slide bar 23 is formed with gear teeth 29 on the lower side thereof, and a spur gear 30 which is fixed to a shaft 3| meshes with the teeth 29 of the slide 23. The shaft 3| is journalled through the vertical side walls of the housing 26 and has secured to the outer end thereof a knurled knob 32. The housing 26 is formed with end flanges 33 having vertically elongated openings 34 therein through which securing means 35 extend so that the housing 26 may be vertically adjusted in order to dispose the pointer H in a coplanar position with respect to the writing line of the type on the paper l3. The slide 23 includes a depending end flange 36 through which an adjustable stop bolt 31 is threaded, and the head of the bolt 3'! is adapted to engage the adjacent end wall 38 of the housin which is formed with an opening 39 so that the stop member 31 may be adjusted to provide for limiting the forward movement of the slide 23.

During the normal typing operation the slide 23 will be retracted or moved to the left as viewed in Figure 1 so as to dispose the pointer [4 a substantial distance rearwardly of the platen l2 and the paper l3. When it is desired to relocate the paper l3 so as to either make corrections on the paper or to place additional typing thereon, the slide 23 is moved forwardly to the limit permitted by the stop member 3?. At this time the pointer M will be disposed closely adjacent the paper l3, and in the event there is a period or a comma in the type line the period is disposed in a position confronting the forward end of the pointer Hi.

The housing 26 is preferably formed with two pairs of guide bars 24 and 24a, and the bottom Wall 4!! of the housing is provided with an elongated opening 21a in order that the same housing may be used on either side of the machine. It is contemplated that there be two of these 1ocating devices on the opposite sides of the cover ll so that the paper 13 may be accurately relocated from the adjacent ends of the platen l2.

What is claimed is: l

1. A realigning attachment for typewriters comprising a housing adapted for mounting on a side of the typewriter confronting the platen, guides in said housing, a gear rack slidably engaging said guides, a pointer, means securing said pointer to said rack in a position confronting the typing line, a spur gear meshing with said rack, and an operator for said spur gear.

2. A realigning attachment for typewriters comprising a housing adapted for mounting on a side of the typewriter confronting the platen, guides in said housing, a gear rack siidably engaging said guides, a pointer, means securing said pointer to said rack in a position confronting the typing line, adjustable stop means for limiting the forward movement of said rack, a spur gear meshing with said rack, and an operator for said spur gear.

3. A realigning attachment for typewriters comprising a housing adapted for mounting on a side of the typewriter confronting the platen,

guides in said housing, a gear rack slidably engaging said guides, a pointer, means securing said pointer to said rack in a position confronting the typing line, a threaded stop member carried by said rack, said housing having an opening through which said stop member may be adjusted, a spur gear meshing with said rack, and an operator for said spur gear.
